JULIUS A. KENNEDY, OE MAIDEN, NORTH CAROLINA, ASSI GNOR OF ONE- IIALE TO GEORGE W. LAMANOE, OF SAME PLACE.

DAM PER FOR FIREPLACES.

SPECIFICATION forming part of Letters Patent No. 624,049, dated May 2, 1899.

Application filed April 9, 1898. Serial No. 677,025. (No model.)

of North Carolina, have invented a new and.

useful Damper for Fireplaces, of which the following is a specification.

The invention relates to improvements in dampers for fireplaces.

The object of the present invention is to provide for fireplaces a simple, inexpensive, and efficient device adapted to regulate the draft, prevent a too-rapid burning of the fuel, and throw the heat which would otherwise pass up the chimney out into the room.

The invention consists in the construction and novel combination and arrangement of parts, as hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a vertical sectional view of a chimney and fireplace provided with a device constructed inaccordance with this invention. Fig. 2 is a transverse sectional view. Fig. 3 is a detail view of the damper.

Like numerals of reference designate corresponding parts in all the figures of the drawin gs.

1 designates a damper constructed of sheet metal and arranged in a chimney 2 at the top of a fireplace 3 and adapted to regulate the draft, and thereby control the burning of fuel and prevent a large amount of heat from escaping at the chimney. The damper, which has its front edges rolled at opposite sides of the center to form eyes 4, is mounted on a transverse pintle-rod 5 and is hinged by the same to the fireplace or chimney. The outer ends of the pintle-rod are arranged in recesses 0r sockets of the walls of the fireplace, and the said rod is composed ofend sections 6, connected by a central adj ust-able section 7, which is tubular. The inner portions of the end sections 6 are provided with right and left hand screw-threads S and 9, and the tubular central section is correspondingly threaded, whereby it is adapted to move the end sections simultaneously inward and outward to vary the length of the pintle-rod.

The damper is maintained at any desired and the handle 11, which is constructed of resilient metal, is adapted to be sprung into and out of engagement with the teeth of the ratchet to adjust the damper. The handle, which may be secured to the damper, is preferably provided with an arm 12, which is passed through perforations of the damper, as shown, and has its terminal bent-on itself to form a stop and prevent the arm from being withdrawn from the perforations.

The invention has the following advantages: The dam per, which is simple and coinparatively inexpensive in construction and which is design ed to be constructed in various sizes to suit different fireplaces, may be readily applied to the same as the pintle-rod is adjustable and is adapted to be firmly fixed in recesses in the opposite walls of a fireplace or chimney by adjusting the central section. The handle is adapted to be readily sprung into and out of engagement with the ratchet, which has its teeth shouldered at the inner side and which is adapted to support the dam per at any desired adjustment.

The damper, which is adapted to be employed when either wood or coal is used as a fuel, is capable of regulating the draft and of controlling the burning of the fuel, and it is also adapted to prevent a large amount of heat from passing up the chimney and will deflect the same into a room. Also after the gas and smoke have escaped from the fuel the damper may be entirely closed, so that all the heat will be thrown out into the room.

Changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having thus fully described the invention, what is claimed as new is- 1. A device of the class described comprising a damper designed to extend across the top of a fireplace and provided at its front edge with eyes spaced apart, and a pintle-rod for hinging the damper in a fireplace, said pintle-rod comprising end sections arranged IOC in the eyes of the damper and extending beyond the same to engage the Walls of a fireplace and provided at their inner ends with right and left hand threads, and a central tubular section arranged between the eyes and provided with right and left hand threads to engage those of the end sections, substantially as described.

2. A device of the class described comprising a damper designed to be arranged at the top of a fireplace and hinged at its front edge to the same, said damper being provided with openings, a stationary curved ratchet located beneath the front hinged edge of the damper and designed to be fixed to one of the side walls of the fireplace, and the resilient handle 11 depending from the front edge of the dam per and engaging the curved ratchet, said handle having an arm, disposed transversely of the damper, extending through the openings thereof and having its end bent around the edge of the damper to form a stop, substantially as described.

3. A device of the class described, comprising a damper designed to extend across the top of a fireplace and provided at its front edge with eyes spaced apart, and a pintle-rod for hinging the damper to the fireplace, said pintle-rod comprising end sections arranged in said eyes, and a central section adjustably connected with the inner terminals of the end sections and adapted to move the latter inward and outward whereby the damper is detachably hinged in the fireplace, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.

JULIUS A. KENNEDY.
